Actually, I'm a bit surprised that they worked at all. The high density
disks use a different media with a different coercivity. I've never been 
able to, for instance, format a 1.44M 3.5" disk at 720K. My boss, an
analog guy, mumbled things about filter frequencies and how the head and
media form some kind of filter, but I didn't understand it. I'm just a
lowly software type.
